Question

What is the longitude of a town x who's time is 12:00 pm noon when Greenwich meridian time is 6pm

Answer 1

Explanation:

To avoid confusion it’s probably best to describe “12:00” as “noon” or “midnight”. But I’ll assume you mean noon.

So that’s six hours behind GMT.

Note how timezones work. You can’t tell the exact longitude. If we used exact time based on the sun or something, different suburbs in large cities would have different times. It would be very confusing. So the world is broken up into different timezones. In theory there would be one for every hour, with the the one around the International date line split between +12 and -12 (ie the two sides having the same time but one day apart)..

In practice though it’s more complicated than that. Each country (and sometimes each state/province) has the right to set its own time. So the time often doesn’t match exactly what the time “should” be. The obvious example is China, which is large enough to have four timezones, but only uses one because the government wants all of China to be unified, which includes them all having the same time. This means that in the far west people start work really late (according to the official time) and finish really late.

This is also how lots of countries have summer time.

There are very many maps that show the world’s timezones, for example this site that I just found now by googling: World Time Zone Map

There are lots of weird things about timezones, that aren’t really relevant to this question.

Anyway, the timezone you ask about, GMT —6, is here: UTC−06:00 - Wikipedia Note the map partway down the article.

As the map shows, in summer the map extends in places from even further west than Longitude 135 West (in northern Canada) to 82.5 degrees West. In winter, the eastern border is the same (82.5 degrees West) but the westernmost bit of land is Easter Island of a bit over 109 degrees West.

So a town (at least if you include small arctic settlements) can be anywhere between those longitudes and be at 12 noon when UTC (ie GMT) is at 18:00 (note that Greenwich does not always use GMT).

Answer 2

Answer:

6AM or 6PM in Greenwich…?

If it’s 12 noon in the town, and 6PM in Greenwich then it’s 6 hours *ahead* of Greenwich, so the longitude would be about 90 degrees East.

If it’s 12 noon in the town, and 6AM in Greenwich, then it’s 6 hours *behind* of Greenwich, so the longitude would about 90 degrees West.
